That's not even 2.5D.
2.5D started with Doom and it refers to games where you can move on Z axis, but can never be at the same XY point at more than one Z. That is you can't walk under or over some other path.
- bluedino 8y agoThe way sectors work in doom you can't have one floor above another (like a bridge), however, you can fan fall off a ledge.
- eps 8y agoSure. You can’t get under the ledge though. I don’t remember full details, but the gist of it was that Carmack optimized rendering algorithm around this specific restriction.
